Title: Optical disk device
Inventor: YAMADA KUNIO
IPC: G11B7/00
Filed: 1992-01-24
Abstract: PURPOSE:To eliminate a disk inclining component and to remarkably increase an inclining allowable value by taking out a difference output in the tracking direction of multidivided phototdetectors and a sum output of one pair of the detectors, giving the sum output a DC bias and multiplying this result by the difference output. CONSTITUTION:Reflecting light of an optical disk 1 is led to bisected photodetectors 7. Outputs 8S and 9S are obtained from outputs of the detectors 7A and 7B via a differential amplifier 8 and an addition amplifier 9. A DC current of the signal 9S is cut by a capacitor 22, and is impressed with an appropriate DC bias voltage by DC power sources 25A and 25B and a variable resistor 24 to form a signal 23 in a bias means 30. The signal 8S and the signal 23 are multiplied by a multiplier 20 to take out a tracking error signal 21. In a tracking driving circuit 10A, a high frequency component of the signal 23 is eliminated by an LPF, and a tracking actuator 11 is driven, and then an objective 6 is moved in a direction so as to control a light point center and a track center to be coincident with each other. By this constitution, a signal based on an inclination of the disk 1 is not included in the signal 21, and a true track error signal is detected and the inclining allowable value can be widen.
